NOT_READABLE properties are not properly audited

[pavelhoral]

Right now the activity audit works based on object before a and object after states. That means if there are attributes marked as NOT_READABLE, those will never get included in the audit record. Fields marked as not readable might be important fields like userPassword, which means that passwordchanged audit flag won't be filled.

Relevant references:

• ObjectClassResourceProvider
• RouterActivityLogger

Suggested fix:

Change detection should take fields from the request into account (i.e. sending update/patch/create request field names to audit service together with before and after object state).
